Qualcomm atheros ar. I have an aspire v. G, have had it since Jan and nothing I have done so far seems to fix the Wi. Fi. I have tried multiple drivers, upgrading/downgrading them never seemed to change the outcome, constant drops every 5 minutes. Doesn't show a lose in connection or a drop in signal, but downloads and streaming content hang and sometimes fail due to lost connection. Haven't tried the BIOS upgrade but I'm not sure if that will really help.

Contacted acer and they said if they serviced it and found it to be a software problem and not hardware they would charge me around . So fed up with it. If anyone has a possible fix for this please share, I have got to the stage where I will try anything. Sorry for the long post... I had, as many others, exactly the same problem you have (or had, don't know if you solved eventually).

I have tried ALL drivers release over internet, and read tons of post of ppl suggesting different solutions, but nothing worked for me until I have found the right one on an italian forum (www. I have already wrote a post explain what is the real problem and how to solve it.. Notebooks- Netbooks/Acer- wifi- limited- connectivity- issue/m- p/1. M2. 59. 59. Making a brief resume, just to be sure in case Acer decide to delete the post (I have not been so kind : P), the real problem is that the driver cannot switch between the two antennas properly, so each time the Diversity take in account, the connection get lost. Right now, at release 1. The solution is pretty tricky, and maybe a little scary for someone, but it is actually easy and fast: open your laptop, disconnect one on the antennas cable (the black one, the auxillary antenna), put some tape to ensure isolation, close and enjoy.

You will not loose anything, as the Antenna Diversity is something good when properly done, so with two different receivers. In the Qualcomm board is not like that, is one receiver with a signal switch that has a signal loss surely bigger than the double antenna advantage.. I did it on mine, and many other people on theirs, right now no one complains and no disconnection at all (yesterday night, for the first time since when I bought this ugly laptop, I have been able to watch a full movie without any disconnection.
